  Q: How to Replace a Control Arm Bushing on a Solid Rear Axle on Chevrolet Uplander?

  A:

  Rear axle maintenance starts by lifting the vehicle for support then positioning a utility stand to hold the Control Arm slightly in front of the coil spring. First remove the rear axle bolts from the Control Arm and then use a utility stand to lower the axle to get to the Control Arm bushing. Begin by recording the Control Arm bushing's position on the lower arm before using the rear suspension bushing remover/installer (3GJ 28685) paired with the ball joint remover/installer kit (3GJ 9519-E) to uninstall the bushing. The flat section of the new bushing needs to face the fluid axis at a 90-degree angle that is nine degrees off from the Control Arm's centerline during installation. Use the same tools of rear suspension bushing remover/installer (3GJ 28685) and ball joint remover/installer kit (3GJ 9519-E) to install the bushing which must reach 30 mm (1.18 in) beyond the Control Arm. The bushing requirements call for installation completion once its end points at the indicator line marked on the j28685. Install the bolt to the rear axle by raising it with the utility stand while the vehicle is lowered.
